Circuit Protection

When an electrical circuit overload occurs, the amount of electrical current flowing in the circuit exceeds the safe limits intended by the designer of the circuit and manufacturer of the cabling and components within the circuit. Overload (depending upon frequency and magnitude) can cause a variety of damage to electrical wiring, systems, and components.

As we can see from the diagram above, the wiring for the socket outlets begins at the consumer unit and loops into and out of each socket before continuing onwards around the ring. Finally, the cable leaves the last socket and returns to the consumer unit. Inside the consumer unit, there is a circuit breaker (a type of overcurrent protective device) that prevents overload and short circuits from occurring on the ring final circuit.

When planning a new kitchen, most people focus on layouts, appliances, and finishes. However, an often-overlooked aspect of a kitchen renovation is the state of the home’s electrical system. With modern kitchens requiring more power for appliances and lighting than older kitchen designs, your old fuse box or consumer unit might not be up to the task. As an experienced electrician and tutor, I’ll Walk you through the key considerations and why upgrading your electrical panel is often a smart, and sometimes necessary, step.
